A lot of the continued issues we see now are reasons why I didnt think it was right to get rid of Koeman. Walsh is the main perpetrator behind what has gone wrong, and with each passing transfer it becomes more and more evident. The bloke has been given too much responsibility based on the fact he got a few decent players in at Leicester, it might be that Klasseen, Sandro, Tosun, Keane et al will turn out to be amazing next year but I dont think we can afford to go through this year again with so many failures.
Koeman wasn't getting the best out of what he had though. The team was dysfunctional, low on morale, had no shape and we weren't winning football matches. Regardless of whose fault that was (and I agree Walsh has to take the lions share of the blame) if you're losing football matches regularly you need to change something and as you can't change the players mid-season, and binning the DoF wouldn't have affected what happens on the pitch, then it had to be the manager.
